Guide Prices for OPC Toolkits

We no longer show individual vendors' prices for most toolkits, and instead give guide prices for different types of toolkit, irrespective of supplier. There are a number of reasons for this:

• Some vendors will not release pricing information at all, while others will only do so under duress.
• Many customers will negotiate discounts when buying toolkits, so the quoted price is really only a maximum price in any case.
• OPC toolkits are arguably now a commodity item, and prices from different vendors are broadly similar. That's not to say that you won't find differences in quality from different vendors.

So what are our guide prices? We believe you should pay no more than these prices for OPC toolkits:

Client Toolkit	1250 USD
Server Toolkit ('rapid' development model, incomplete source)	1250 USD
Server Toolkit (fully featured, with source)	4500 USD

You should expect a substantial discount if buying two or more toolkits as a bundle. Similarly, you may pay a slight premium if support is offered for two or more OPC specifications within the same toolkit.

A newer toolkit type extends the rapid development model by packaging the core server functionality as an ActiveX control. This approach allows the use of Visual Basic for server development. It is less easy possible to offer a guide price for this toolkit category, though you should certainly not pay more than for an equivalent rapid development toolkit.

MatrikonOPC

OPC Genie

Matrikon's OPC Genie (Generic Information Exchange) enables the exchange of process data between OPC compliant applications and any device that supports serial or Ethernet communication. This flexibility enables you to develop an OPC server without sacrificing throughput or data integrity. Simply configure OPC Genie with the required protocol and all the data will be exposed via OPC!

No programming is required. Refer to the OPC Genie page for more information.

Advosol

OPCDA.NET, OPCHDA.NET, OPCAE.NET

Advosol's .NET client products offer the capability to develop DA, HDA and AE clients using Microsoft.NET. See our .NET page for more information.

OPCDA.NET Server Toolkit, Historian .NET Server Toolkit

Advosol's DANSrv (OPCDA.NET Server Toolkit) and HDANSrv (OPC HDA. NET Server Toolkit) provide .NET developers with the ability to build their own Data Access and HDA servers using exclusively .NET languages (VB.NET and C# are supported). See our .NET page for more information.

XML-DA Rapid Server Toolkit

This XML-DA Rapid Server Toolkit is an ASP.NET module: a native .NET web service which makes no use of COM. The developer provides a customization component written using any .NET language. Only five functions must be implemented, and the same customization module may also be used with Advosol'sOPCDA.NET COM server. Also available as a 'Professional' edition, with more options for customization.
